Mmmm, appreciate it Tortuga, but I'll decline. I don't think a thermal lance is an oxy acetylene torch. It might be lit by one. And I think it can cut steel and concrete, from what I glean from my initial research. Yes, noise will be a problem, but now I'm considering a diamond core driller for the building's footings, then continue with the diamond drill until it can't handle the vault walls. Then, I'll use the thermal lance to complete entry to the vault. Explosives, ChrisK? Maybe, but probably not. I have an actual bank in London and the building next to it. The file gives you some idea of the logistics The Vault.pdf The Vault.pdf

Well, thank you both. I recognize this is not an easy subject and I also saw the problem with noise. Won't the thermal lance take care of the concrete with embedded rebar? They're not in a hurry, so time is not a problem. Noise will be the problem. "Inside Man" was an enjoyable movie, but not my story. 😀

Thank you for allowing me to intrude, everyone. I'm beginning my fourth book (a novel), set in London 1968. For a bank heist, I need to cut through the foundation of a building (concrete slab?) and then through the wall of the vault. I've been looking at cutting tools (maybe a Skil Heavy Duty Roto-hammer or a Bosch Brute Breaker hammer), then a thermal lance to cut through the strengthened wall of the vault. Does this sound reasonable, or can you suggest a more obvious choice? Regards and much appreciation of any wise suggestions. Sean
